Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
1. Participants in a fasting state (minimum 8 hours, no food, water only) will be prepared for cannulation. The participants are either called or text messaged to remind them of their study fasting requirements. An intravenous cannula will be inserted into the arm vein using standard cannulation procedures (Guideline for PIVC Insertion and Post Insertion Care in Adult Patients, NSW Health) by a trained phlebotomist.
2. Baseline blood samples (25 mL) will be obtained and the participants will consume a serving of plain cooked coloured rice (one cup or 200 g) and have 20-minutes to consume the rice serving.
3. After rice consumption, blood samples (25 mL at each time point) will be taken at regular time intervals 0.5, 1, 2 ,4 ,6 hours post rice consumption.
4. The cannula will be removed and the site covered with sterile gauze.
5. A one week of wash out between cross over 2 (week 2 - day 7) and 3 (week 3 - day 14) will be applied. The order of rice varieties (black, red and brown rice) served to the participants is randomised for each participant over the 3 weeks (e.g. Participant 1 - Purple, brown, red; Participant 2 - red, purple brown). This randomisation is completed using Microsoft Office Excel.

Outcomes
Primary outcome [1] 321502 0
Cell adhesion molecules (ICAM, VCAM) levels assessed by ELISA of plasma. This is a composite primary outcome.
Timepoint [1] 321502 0
Acute intervention dietary trial
Week 1 - Coloured rice 1 (black, red or brown depending on randomisation assignment) - same day
Week 2 - Coloured rice 2 (black, red or brown depending on randomisation assignment) - same day
Week 3 - Coloured rice 3 (black, red or brown depending on randomisation assignment) - same day
Blood samples will be collected at 0.5, 1, 2 ,4 hours post rice consumption (during each intervention bout).
Primary outcome [2] 321503 0
Exploratory examination of oxidative stress biomarkers (SOD-1) as assessed by ELISA of plasma.
Timepoint [2] 321503 0
Acute intervention dietary trial
Week 1 - Coloured rice 1 (black, red or brown depending on randomisation assignment) - same day
Week 2 - Coloured rice 2 (black, red or brown depending on randomisation assignment) - same day
Week 3 - Coloured rice 3 (black, red or brown depending on randomisation assignment) - same day
Blood samples will be collected at 0.5, 1, 2 ,4 hours post rice consumption (during each intervention bout).
Primary outcome [3] 321504 0
Inflammatory biomarkers (IL-6, IL-8) antibody capture bead kit performed on plasma samples and obtained via flowcytometric methods. This is a composite primary outcome. as the kit can quantify multiple cytokines with the one plasma sample.

Efficacy
Statistical methods / analysis
A minimum sample size of 21 volunteers is required for 80% power to detect a 5% variation in the laboratory parameters measured, where a 3–5% standard deviation exists in the population, assuming an alpha error of 0.05.
Graph Pad Prism statistical analysis software will be used to evaluate the impact of the acute intervention of coloured rice. Analysis of variance (ANOVA) coupled with post-hoc analysis will be employed.
